Hypodermic vein detection imaging apparatus based on infrared optical system

Abstract

The present invention is to provide a hypodermic vein detection imaging apparatus capable of visualizing a vein under the skin. The hypodermic vein detection system according to the present invention comprises a hypodermic vein detection imaging apparatus ( 10 ) comprising a dome-shaped holder ( 12 ), a plurality of infrared light sources ( 11 ) arranged at a uniform interval in a circumferential direction on the inner surface of the dome-shaped holder ( 12 ), a motor driving unit ( 13 ) for rotating the dome-shaped holder ( 12 ), teeth ( 14 ) meshing with the motor driving unit and formed on the dome-shaped holder ( 12 ), an optical zoom lens ( 15 ) positioned at the center of the top of the dome-shaped holder, an infrared transmitting filter ( 16 ) for filtering light transmitted through the optical zoom lens ( 15 ), a first image detector ( 17 ) receiving light filtered by the infrared transmitting filter ( 16 ), and an image display device ( 10 ) for visualizing digital image information obtained by the first image detector ( 17 ).

The invention claimed is: 
     
       1. A hypodermic vein detection imaging apparatus comprising
 a dome-shaped holder ( 12 ) including teeth ( 14 ) formed on the dome-shaped holder's upper surface, a plurality of infrared light source ( 11 ) arranged at an uniform interval in a circumferential direction on the inner surface of the dome-shaped holder ( 12 ), a motor driving unit ( 13 ) for meshing with the teeth ( 14 ) so as to rotate the dome-shaped holder ( 12 ), 
 an optical zoom lens ( 15 ), an infrared transmitting filter ( 16 ), a first CCD digital camera ( 17 ) positioned fixedly in sequence in a direction away from the dome-shaped holder ( 12 ), and 
 an image display device for visualizing a digital image information obtained by the first CCD digital camera ( 17 ). 
 
     
     
       2. The hypodermic vein detection imaging apparatus according to  claim 1 , wherein the infrared light sources ( 11 ) are LED. 
     
     
       3. The hypodermic vein detection imaging apparatus according to  claim 1  or  2 , further comprising a processing device comprising a program capable of processing the digital image information obtained by the first CCD digital camera ( 17 ). 
     
     
       4. The hypodermic vein detection imaging apparatus according to  claim 1  or  2 , further comprising
 an optical splitter ( 18 ) positioned between the optical zoom lens ( 15 ) and the infrared transmitting filter ( 16 ), 
 a second CCD digital camera ( 19 ) receiving light splitted and reflected by the optical splitter ( 18 ), 
 a processing device provided with a program capable of combining black and white image of a vein obtained by the first CCD digital camera ( 17 ) and natural color image of a skin obtained by the second CCD digital camera ( 19 ) to visualize it on the image display device. 
 
     
     
       5. The hypodermic vein detection imaging apparatus according to  claim 1  or  2 , wherein the first CCD digital camera ( 17 ) and the image display device are connected through a detachable connecting unit,
 the connecting unit is formed as a flexible goose-neck type tube. 
 
     
     
       6. The hypodermic vein detection imaging apparatus according to  claim 5 , wherein the image display device is the form of goggle which user is able to wear.
